Num 23:19 God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?

Heb 6:18 That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:

Tit 1:2 In hope of eternal life, which God, that cannot lie, promised before the world began;

God is faithful

1Co 1:9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.

1Co 10:13 There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.

2Th 3:3 But the Lord is faithful, who shall stablish you, and keep you from evil.

1Jn 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
